Flu shot: Your best bet for avoiding influenza

Getting a flu shot often protects you from coming down with the flu. And while the flu shot doesn’t always provide total protection, it’s still worth getting..

by the Mayo Clinic

The Food and Drug Administration (FDA) has approved the vaccines that will be available this fall to protect people against several seasonal flu (influenza) viruses expected to be in circulation this fall and winter.

This annual flu shot won’t contain protection against the pandemic swine flu (novel H1N1) virus. A separate vaccine has been developed for the swine flu virus.

Influenza is a respiratory infection that sickens millions of people each year and can cause serious complications, especially in children and older adults. Fortunately, the flu vaccine — available in the form of a flu shot or a nasal spray — offers protection against the flu.

Here are the answers to common questions about flu shots.

When is the flu vaccine available?
The flu vaccine is generally offered between September and mid-November, which is typically before the late-fall to early winter start of flu season. However, getting a flu shot even later in the flu season may still protect you. It takes up to two weeks to build immunity following a flu shot.

Why do I need to get vaccinated every year?
You need annual flu protection because the influenza virus changes from year to year. The flu vaccine you got last year wasn’t designed to fight the virus strains in circulation this flu season.

Influenza viruses mutate so quickly that they can render one season’s vaccine ineffective by the next season. A Centers for Disease Control and Prevention (CDC) advisory committee meets early in the year to estimate which strains of influenza virus will be most prevalent during the upcoming flu season, and manufacturers produce vaccine based on those recommendations.

Who should get the flu vaccine?
Most people who want to reduce the risk of getting influenza can get a flu shot. The CDC recommends the flu vaccine each year if you:
- Are age 6 months up to 19 years
- Are pregnant
- Are 50 years old or older
- Have a chronic medical condition such as asthma, diabetes, or heart, kidney or lung disease
- Have a weakened immune system such as from some medications or HIV infection
- Are a resident of a nursing home or other long term care facility
- Are a child care worker or health care worker or live with or care for someone at high risk of complications from the flu

Who shouldn’t get the flu shot?
Don’t get a flu shot if you:
- Have had an allergic reaction to the vaccine in the past.
- Are allergic to chicken eggs.
- Developed Guillain-Barre syndrome, a serious autoimmune disease affecting the nerves outside the brain and spinal cord, within six weeks of receiving the vaccine in the past. People who have experienced Guillain-Barre after the flu vaccine are at higher risk than are others of developing it again.
- Have a fever. Wait until your symptoms improve before getting vaccinated.

What are my options for the flu vaccine?
The flu vaccine comes in two forms:

A shot. A flu shot contains an inactivated vaccine made of killed virus. The injection is usually given in the arm. Because the viruses in the vaccine are killed (inactivated), the shot won’t cause you to get the flu, but it will enable your body to develop the antibodies necessary to ward off influenza viruses. You may have a slight reaction to the shot, such as soreness at the injection site, mild muscle ache or fever. Reactions usually last one to two days and are more likely to occur in children who have never been exposed to flu virus.

A nasal spray. Administered through your nose, the nasal spray vaccine (FluMist) consists of a low dose of live, but weakened, flu viruses. The vaccine doesn’t cause the flu, but it does prompt an immune response in your nose and upper airways as well as throughout your body.

What kind of protection does the flu vaccine offer?
According to the CDC, when the match between flu vaccine and circulating strains of flu virus is close, a flu shot is between 70 and 90 percent effective in warding off influenza in healthy people under age 65.

The flu vaccine is less effective:
- When the vaccine isn’t a close match to the type of flu viruses circulating in the community
- In people over the age of 65
- In people with compromised immune systems
- Why do children need two doses of the flu vaccine?
- Children younger than 9 years old require two doses of the flu vaccine if it’s the first time they’ve been vaccinated for influenza. That’s because children don’t develop an adequate antibody level the first time they get the vaccine. Antibodies help fight the virus if it enters your child’s system. If a flu vaccine shortage were to occur and your child couldn’t get two doses of vaccine, one dose might still offer some protection.

I heard the flu shot isn’t very effective for older adults. Is it worth getting vaccinated if you’re over 65?
If you’re over age 65, the vaccine doesn’t offer as much protection as it would to someone younger because older adults produce fewer antibodies in response to the virus. Still, the vaccine offers more protection than does skipping the shot altogether. More important, the flu vaccine decreases the risk of flu-related complications — especially pneumonia, heart attack, stroke and death — to which older adults are especially vulnerable.

Can I lower my risk of the flu without getting a flu shot?
With or without a flu shot, you can take steps to help protect yourself from the flu and other viruses. Good hygiene remains your primary defense against contagious illnesses.
- Wash your hands thoroughly and often with soap and water or an alcohol-based sanitizer containing at least 60 percent alcohol.
- Avoid touching your eyes, nose or mouth whenever possible.
- Avoid crowds when the flu is most prevalent in your area.
- Cover your mouth and nose with a tissue when you cough or sneeze.

What you don’t know can hurt you. Ventura County’s lesser-known and most popular STDs

By Kit Stolz, 07/30/2009

The most feared of all sexually transmitted diseases (STDs) is the potentially deadly AIDS/HIV virus, which in 2005 struck 30 people in Ventura County, according to the Department of Public Health.

That, ironically, is the good news. The rate of AIDS/HIV infection has stabilized in recent years, and even declined slightly from that of five years ago.

The bad news is that more than 50 times as common as the HIV/AIDS virus is a sexually transmitted bacteriological disease called chlamydia. Chlamydia is epidemic in the United States, and the rate of infection in Ventura County has doubled in the last 10 years.

Chlamydia was diagnosed in 1,570 people in Ventura County in 2005, the most recent year for which there are official statistics. Most of those who contracted the disease were young. Nearly one-quarter of those who came down with the sexually transmitted disease (STD) were teenagers, and almost one-half of those who contracted the STD disease were between the ages of 20 and 24.

It’s the most frequently reported of all sexually transmitted diseases (STDs), both nationwide and in Ventura County. Although it’s not the most common of sexually transmitted diseases (STDs), it’s one of the most likely to cause problems if not treated.

The real hazard of chlamydia is not that so many people have it and know it, but that a far larger number of people have it and don’t know it.

“It’s one of the most common infections we see,” said Dr. Kirk Cook, who works as a family doctor and serves as a public information official for the county, “but the number of cases we see is just a fraction, because most people who contract this disease do not have symptoms.”

According to the U.S. Centers for Disease Control, about three-quarters of infected women and about one-half of infected men do not show signs of chlamydia.

If symptoms do appear, they show up within one to three weeks after infection.

In women, medical experts say that the most common symptom is a vaginal discharge, pain during urination, pelvic pain or pain during sex.

In men, the most likely symptom is a burning experienced during urination. Because men’s sexual organs are simpler, the disease is more likely to be seen, but symptoms can vary. One Ventura County patient, who wished to keep his identity private, found a sore on his penis after a sexual adventure overseas.

“It didn’t hurt, but it was gross,” he said. “I couldn’t believe it. I never saw anything like it. It looked like a crater on my dick. It just got bigger and bigger. I had to go to the doctor.”

Easy to cure and easy to contract, again Chlamydia is one of the easiest of all sexually transmitted diseases to treat. A single dose of an antibiotic pill named azithromycin can cure the disease, although doctors typically ask patients to return to take a second dose of the medicine, because one-quarter or more of those who are initially diagnosed with the disease are reinfected within months, usually by the same partner who passed on the disease in the first place.

“In California, the largest population affected by this disease are in the ages of 15-25,” said Cook. “I think that’s partly because these are people who are not mature adults, and also because chlamydia is not a disease that kills people, the way the HIV/AIDS virus can, so it’s easy to get complacent. But if this disease goes untreated in women, it can lead to pelvic inflammation and scarring of the fallopian tubes. This is a disease with bad long-term consequences for fertility.”

If a woman has no symptoms, or overlooks cramping, pain or a bloody discharge, the chlamydia infection can spread, often resulting in PID, or pelvic inflammatory disease, which can damage a woman’s reproductive organs. According to the Guttacher Institute, an international nonprofit organization focused on sexual health, about 20 percent of women who contract PID will lose their fertility permanently.

Why patients often don’t know who gave them the STD Disease
According to Dr. Adina Nack, a sexual health educator at Cal Lutheran University who published a book last year about women’s experiences with sexually transmitted diseases such as HPV, the human papillomavirus, STDs can remain hidden in the body and without symptoms for so long that a patient often isn’t sure who gave him or her the disease.

“One of my interviewees had been married once, gotten divorced, and then when she was with her second husband came down with symptoms of a sexually transmitted infection,” Nack said. “We tend to think that if we are exposed to one of these diseases, that we will get the symptoms within a short period of time, but it’s very possible to be exposed to an STD and not see your first symptoms for upwards of 18 months.”

This was the case of one young Ventura County woman, “Helen,” who had gotten engaged to be married when she suffered her first outbreak of genital herpes. She assumed at the time that her fiance had given her the disease, despite his denials, but now realizes that she probably picked it up when she was an undergraduate in college.

“It was horribly painful, and I blamed him,” she said. “I had no idea what was happening to me — I didn’t know anybody who had had herpes. It caused a lot of stress in the relationship, and we eventually broke up.”

Genital herpes is not on the list of sexually transmitted diseases reported to government medical authorities because, according to the Centers for Disease Control, blood tests for genital herpes can be “difficult to interpret.”

Blood tests can detect the presence of antibodies to herpes, but cannot reliably distinguish between herpes simplex type 1, which is more likely to cause fever blisters around the mouth, and herpes simplex type 2, the virus which usually causes genital herpes.

The virus is the most common sexually transmitted disease, infecting an estimated 45 million to 60 million Americans, according to the CDC.

Herpes can be passed on even if no symptoms are present. Although antiviral prescription drugs such as Valtrex can make the disease less painful and contagious, it’s still a disease profoundly damaging to what Nack, in her book Damaged

Goods, calls a woman’s “sexual self.”

An older woman in the San Fernando Valley, “Jamie,” wrote in an e-mail interview how she was devastated by a diagnosis of herpes simplex type 2 from a lover who died before she found out that he gave her the sexually transmitted disease.

“I was so wounded that I shut down socially. I had no social life for many years and did not even think about dating. I could not begin to imagine the misery and humiliation of having to have that infamous ‘talk’ that we, who know we have herpes, are supposed to have with a potential mate or lover. It is ironic because those who are spreading it are those who do not know they have it, which is most people with herpes,” she said.

Recovering from a sexually transmitted disease (STD)
According to Nack, the emotional devastation “Jamie” experienced when she caught a sexually transmitted disease is often what happens to women who contract STDs. Nack thinks this reflects the way we as a people have decided to look at sexual health.

“In this country, we consistently want to hold women responsible for sexual health, but not their male partners,” she said. “You can see this attitude play out with the Gardasil vaccine, which can protect against HPV (human papilloma virus, aka genital warts) in both men and women, but which has been marketed only to young women, and not as an HPV vaccine, but as a cancer vaccine. I don’t think we’re doing men any favors by letting them off the hook when it comes to taking care of their sexual health. They won’t get cervical cancer, but I have seen some seriously bad cases of genital warts on men.”

Nack points out that more than 6 million new cases of HPV are diagnosed each year, making it the second most common sexually transmitted disease after herpes. Complicating matters is the fact that the test for cervical cancer, the Pap smear, can detect the presence of abnormal HPV-altered cells around the cervix, but cannot detect the genital wart virus on external sex organs. A doctor who isn’t careful can give a patient the impression she doesn’t have HPV when she does, or can lead a patient to fear cervical cancer, when in fact she may only have contracted the virus that can sometimes develop years later into cervical cancer.

All too often, according to Nack’s research, doctors stumble over the complexities and uncertainties of diagnosis of sexually transmitted disease, especially in women. Two-thirds of the more than 40 women she interviewed at length complained that their doctors misdiagnosed their STDs, failed to explain them clearly, or even hurt them unnecessarily in treatment, adding to the pain and confusion.

Patients often go into “diagnostic shock” when they learn they have a sexually transmitted disease, Dr. Cook confirms.

“If a patient has symptoms, sometimes the diagnosis comes as a relief, especially with chlamydia, which is easy to treat,” he said. “But sometimes a patient will say, ‘I don’t even know what you’re talking about,’ or, ‘I never heard of it.’ Part of a doctor’s job is education, and with STDs, that means encouraging patients to contact sexual partners and encourage them to come in for treatment.”

Christine Lyon, of Planned Parenthood in Santa Barbara, points out that young patients are often reluctant to go to their family doctors for tests or treatments, knowing that this will likely spark questions from parents. She encourages young people who suspect they have an STD, or who want to know how to protect themselves, to visit Planned Parenthood or a county health clinic if a visit to a family doctor sounds intimidating.

“One in four young women in this country have an STD,” she said. “A lot of those cases are chlamydia. The known rate of chlamydia is higher in women than in men, but that’s probably because they are more likely to receive routine screening. Our goal is to treat anyone who comes through the door and wants reproductive health services.”

The good news about STDs
Contracting a sexually transmitted disease (STD) often turns out to be a strengthening experience in the long run, according to Dr. Nack. Many of the women she interviewed look back on themselves before they were infected as naive and passive, too compliant to the wishes of men.

“Once you decide you might want to be intimate with someone, you have to have ‘The Talk.’ You have to get your partner to be as honest as possible about their sexual health,” Nack said. “Because there’s a heavy moral stigma against being sexually active, it’s difficult for young girls to take an assertive role, but it’s really necessary. Condoms are great for preventing fluid-borne STDs, such as HIV, chlamydia, and gonorrhea, but skin-to-skin contact still takes place in sex, and that can pass other STDs, such as HPV and herpes.”

“Jamie” completely agrees that women must protect themselves, and objects fiercely to victims of sexually transmitted diseases being blamed for their misfortune.

“The herpes social stigma really makes me mad because it is the only serious harm it does to most people who contract, it,” she wrote. “It is not fair to make us lepers. I hate the stereotype ‘herpes whore.’ I got it while being faithful to a man I loved, a guy who should have gotten a special Oscar for Performance in a Personal Life. If you have sex with anyone — and at some point nearly everyone does — you risk contracting the herpes simplex virus. We are not bad people. We are unlucky.”

“Jamie” has taken to wearing confrontational T-shirts in public places, with slogans such as “VALTREX” or “HERPES DISCLOSURE.” She watches the expressions on the faces of people she passes, curious to see if they’re shocked, horrified or understanding, and gives out information on herpes if they’re curious.

She writes that she has mostly taken this one-woman personal sexual education campaign to places such as Venice Beach, but this summer plans to go to more conservative places.

If you see her, she hopes you will say “hi” and be accepting. She says she is only trying to protect you from the pain and heartbreak of coming down with an STD.
